When the Moon blocks the Sun during an eclipse, utility suppliers have to pull power from the grid to make up for gaps in solar energy.
Being severely sunburnt as a child more than doubles the chance of developing future skin cancer but less than half of primary schools questioned in new research have a sun safety policy.
2024 is a leap year, when the shortest month mops up a bit of leftover time. But the extra day also tells us about space – and our place in it.
Humans have synced their calendars to the sun and moon for centuries, but every so often, these systems need a little correction.
Projects under NASA’s CLPS program – including the Odysseus lander that made it to the lunar surface – will probe unexplored questions about the universe’s formation.
You might hate winter, but at least you know what to expect every year. Other planets have wobbly axes that lead to wild, unpredictable seasons.
The sun is expected to reach its solar maximum in 2025. Recent auroras suggest that the maximum may be bigger than predicted.
Early products focused on tanning. Others roasted you like a chicken. Which of these claims can you remember?
Releasing reflective particles into the upper atmosphere would help us tackle climate change – but it’s not without risk.
A newly discovered planet that should be too big to have formed around a tiny star is throwing into question what researchers know about planet formation.
Viral headlines would have you think Saturn’s rings will vanish in just 18 months. Here’s what that really means and why you don’t need to worry.
A more active Sun could disable satellites and affect electrical grids on Earth.
There’s a flurry of excitement every time a comet comes into view from Earth. But what are these celestial objects, and where do they come from?
Does SPF in makeup and moisturisers provide effective sun protection?
We’re currently a few years into the 25th studied solar cycle. An 11-year period of sun activity, this solar cycle is more active than previously expected.
Among the expert witnesses in our justice system, astronomers play a surprising role. This astronomer provides evidence to several cases per week.
Not all lunar eclipses are alike. An astronomer explains the science behind the slight dimming of the Moon on May 5, 2023.
A new generation of flexible solar cells has been pioneered using a material known as perovskite.
Witnessing a total solar eclipse can be an unforgettable experience – and apparently, quite addictive.
